Hospital-based infection control in veterinary medicine is emerging and the role of the environment in hospital-acquired infections (HAI) in veterinary hospitals is largely unknown. This study was initiated to determine the recovery of Escherichia coli and selected veterinary and zoonotic pathogens from the environments of 101 community veterinary hospitals. The proportion of hospitals with positive environmental swabs were: E. coli--92%, Clostridium difficile--58%, methicillin-resistant Staphylococcus aureus (MRSA)--9%, CMY-2 producing E. coli--9%, methicillin-resistant Staphylococcus pseudintermedius--7%, and Salmonella--2%. Vancomycin-resistant Enterococcus spp., canine parvovirus, and feline calicivirus were not isolated. Prevalence of antimicrobial resistance in E. coli isolates was low. Important potential veterinary and human pathogens were recovered including Canadian epidemic strains MRSA-2 and MRSA-5, and C. difficile ribotype 027. There is an environmental reservoir of pathogens in veterinary hospitals; therefore, additional studies are required to characterize risk factors associated with HAI in companion animals, including the role of the environment.
兽医医学中基于医院的感染控制正在兴起，而环境在兽医医院获得性感染（HAI）中的作用在很大程度上尚不清楚。本研究旨在确定从101家社区兽医医院的环境中分离出大肠杆菌以及选定的兽医和人畜共患病原体的情况。环境拭子检测呈阳性的医院比例分别为：大肠杆菌——92%，艰难梭菌——58%，耐甲氧西林金黄色葡萄球菌（MRSA）——9%，产CMY-2的大肠杆菌——9%，耐甲氧西林中间型葡萄球菌——7%，以及沙门氏菌——2%。未分离到耐万古霉素肠球菌、犬细小病毒和猫杯状病毒。大肠杆菌分离株中的抗菌药物耐药率较低。回收的重要潜在兽医和人类病原体包括加拿大流行菌株MRSA-2和MRSA-5，以及艰难梭菌核糖体分型027。兽医医院存在病原体的环境储存库；因此，需要进一步研究以确定与伴侣动物HAI相关的风险因素，包括环境的作用。
